How OLT To Distinguish Uplink Data From Different ONT ?
The downlink data is simple for ONT because they are broadcast down from OLT, ONT only need to apart the information for itself from all information. However, the upstream flow is different, because the upstream flow will meet problem of information conflict .
The former PON technology adopted TDMA for uplink , the time have to be divided then ONT can distinguish the uploaded data. So how ONT know to send the data? And how it know how long will it take to send the data? This requires an agreement between OLT and ONT to achieve the above functions. What will happen if the OLT assign a long time for the ONT? If the amount of data sent by ONT is relatively large, that is to say, the bandwidth of ONT is relatively large. And the ONT start to send data on the allocated time. However, it will waste the bandwidth when the ONT do not have data to send during the allocate time so other ONT which has large data to send cannot use the same time . This situation will inevitably bring rising costs. So GPON allocate bandwidth based on T-CONT.
With T-CONT, OLT is able to allocate bandwidth based on T-CONT. Of course, one ONT has multiple T-CONT, the benefits is it is able to allocate different type of T-CONT according to the different requirements of the business bandwidth. So T-CONT should have different types, currently there are four basic types of T-CONT: Fix, Assure, Not Assure and Best Effort (Max). They are used to represent different bandwidth allocation policies. What is the difference between them? To describe the difference, DBA has to be mentioned and please refer to another article in our website, Dynamically Bandwidth Assignment of OLT.
